OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 235,228, dated December '7, 1880.

Application filed September 30, 1880. (No model.)

To all whom it may concern:

Be it known that I, DEXTER W. GooDELL, of Florence, in the county of Hampshire and State of Massachusetts, have invented a certain new and useful Improvement in Oil- Stoves, of which the following is a specification.

Oil-stoves which have more than one wicktube. when only one wick or less than the whole number of wicks are lighted, often produce a disagreeable smell of oil or vapor, or else smoke; and the object of my invention is to provide an oil-stove which will produce no smoke or smell when all the wicks are not used.

To this end the invention consists in the combination, in an oil-stove having two or more wick-tubes, with a perforated air-distributer and a diaphragm or plate in which are formed, or to which are attached, cones or airguides, and which is arranged at some distance-above the air-distributer, leaving a space between said air-distributer and said diaphragm or plate, of separate chimneys or flues for said wick-tubes and a partition or partitions placed between adjacent wick-tubes and extending between said air-distributer and diaphragm or plate, whereby the air after passing the portion of the air distributer around any one wick-tube has no access to the other wick-tubes either above or below the said diaphragm or plate.

The partition or partitions may be formed upon the under sideof the diaphragm, or they may be formed on or attached to the perforated air-distributer; but I prefer to cast them in one piece with the said diaphragm.

In the accompanying drawings, Figure 1 represents a central vertical section through an oil-stove embodying my invention, and Fig. 2 represents a perspective view of the diaphragm in an inverted position and detached from other parts.

Similar letters of reference-designate corresponding parts in both figures.

A designates the oil-reservoir, and B B designate wick-tubes, of which only two are here shown, although a greater number might be employed. The wick-tubes are supported upon the reservoir, and are furnished with suitable feeding devices, such as rods a, having ratchet or feed wheels upon them for raising and lowering the wicks.

C designates a diaphragm or plate having attached to it, or, as here represented, formed in it, air-guides or cones C, one for each wicktube.

D designates the drum of the stove. E designates the top, and F F designate flues or chimneys, into the lower ends of which the cones or air-guides C project, each wick-tube having a separate flue or chimney. The diaphragm C, body D, top E, and flues or chimneys F F are all properly fitted and held or clamped together by means of a rod or bolt, G.

H designates a perforated air-distributer, which may consist simply of a piece of tin perforated and fitted over the wick-tubes B B at some distance below the diaphragm or plate C, so as to leave a clear space between the two. As here shown, the outer edge of this perforated air-distributer is turned upward and received within a flange or lip, 12, upon the under side of the diaphragm C.

I designates a sheet-metal deflector, through which the wick-tubes project, and which is arranged slightly below the perforated air-distributer H. This deflector prevents the heat radiated downward from the wick-tubes from striking upon the oil-reservoir and heating the oil therein.

So far as above described, all these parts are not materially, it at all, different from corresponding parts in stoves heretofore in use, and therefore need no more detailed description. In all these stoves, however, the space between the diaphragm C and the perforated air-distributer is open from one wick-tube to the other, and hence when one wick only is lighted air will be drawn through the whole area of the air-distributor, supplying a much greater quantity than is required for proper combustion and causing the stove to smoke.

Again, when the space between the diaphragm and air-distributor is undivided between the wick-tubes, the heat generated by the burning of one wick is freely transmitted to the unlighted wick and oil-vapors generated, which cause a very disagreeable smell. In order to obviate these difficulties I divide the space between thediaphragm and air-distriuterby a partition, 0, arranged between the two wick-tubes. This partition may consist of a separate piece inserted and secured in place; but a convenient way of making it is to cast itin the same piece with the diaphragm C, as here shown. This partition is intercepted in the middle by the head of the bolt G; but the head forms a continuation of the partition and prevents the passage of air. When so constructed the air for each wick is drawn through the air-distributer upon one side of the partition 0 only, and after passing said air-distributer such air has no access to the other wick-tube either above or below the diaphragm or plate.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. In an oil-stove having two or more wicktubes, the combination, with a perforated airdistributer and a diaphragm or plate in which are formed, or to which are attached, cones or air-guides and which is arranged at some distance above the air-distributor, leaving a space between said air distributer and said diaphragm or plate, of separate chimneys or flues for said wick-tubes and a partition or partitions placed between adjacent wick-tubes and extending between said air-distributer and said diaphragm or plate, substantially as and for the purpose specified.

:3. The combination, with the wick-tubes B B, the flues or chimneys F F, and a perforated air-distributer, H, of the diaphragm or plate 0. comprising cones or air-guides C O, and arranged some distance above said air-distributer, and the partition 0, attached to and extending downward from the under side of said diaphragm or plate 0, substantially as and for the purpose specified.
